5.0 out of 5 stars Detailed Product Review: Roundup Weed & Grass Killer Refill
Reviewed in the United States on May 16, 2024
I recently purchased the Roundup Weed & Grass Killer Refill, specifically the 1.25-gallon size, to address some persistent weed issues in my yard. After using it for several weeks in various areas around my property, here’s an in-depth review of its performance, application, and overall value.

Effectiveness

The primary concern with any weed and grass killer is its effectiveness, and the Roundup Weed & Grass Killer does not disappoint. Within 24 hours of application, I noticed a significant wilting and browning of the targeted weeds and grass. By the end of the first week, most of the treated plants were completely dead. This product is particularly effective against a broad range of weeds and grasses, including tough perennial weeds. It works by penetrating the plant’s leaves and traveling down to the roots, ensuring a thorough kill that prevents regrowth.

Ease of Use

The refill format of this product is convenient and user-friendly. I already had a Roundup spray applicator, and transferring the liquid from the refill container to the sprayer was straightforward. The refill container has a spout designed to minimize spills and waste, making the process clean and efficient. The 1.25-gallon size is manageable and provides ample coverage for multiple applications across different areas of the yard.

Application Versatility

One of the standout features of this product is its versatility. I used it in various locations, including flower beds, around trees, along driveways, and on walkways. It performed consistently well across all these areas. However, it’s essential to exercise caution when using it near desirable plants, as the non-selective formula can harm any green vegetation it contacts. Using a targeted spray technique or a shield can help avoid unintentional damage.

Environmental and Safety Considerations

While Roundup Weed & Grass Killer is highly effective, it’s crucial to handle it with care. The product contains glyphosate, which has been a topic of controversy regarding its environmental and health impacts. It’s important to follow the safety instructions on the label meticulously. Wearing protective gear, such as gloves and long sleeves, and avoiding application on windy days can minimize exposure risks. Additionally, keeping pets and children away from treated areas until the product has dried is advisable.

Longevity and Residual Effects

One application of Roundup Weed & Grass Killer typically provides long-lasting results. In my experience, treated areas remained weed-free for several weeks. However, as with any herbicide, reapplication might be necessary for stubborn weeds or in areas with heavy weed pressure. The product does not leave a harmful residue in the soil, allowing for planting new flowers, trees, or shrubs in treated areas after a few days.

Value for Money

Given its effectiveness and ease of use, the Roundup Weed & Grass Killer Refill offers good value for money. The 1.25-gallon size is reasonably priced, especially considering the coverage it provides. Compared to other weed killers on the market, it delivers reliable and consistent results, making it a worthwhile investment for maintaining a weed-free landscape.

Overall

Overall, the Roundup Weed & Grass Killer Refill is a powerful and reliable solution for managing unwanted weeds and grass around your property. Its effectiveness, ease of use, and versatility make it a valuable tool for gardeners and homeowners. While it’s essential to handle the product with care and be mindful of its environmental impact, its performance in eradicating weeds and preventing regrowth is impressive. For those looking for a dependable weed and grass killer, this product is a solid choice.

This product was recommended highly by a neighbor with weed problems in their landscaping beds, concrete floor slabs, etc.

Easy to use. I'd recommend a 1 gallon sprayer with this. This product is a "Concentrate" meaning you can make the solution as strong or weak as needed.

Well I live in South Florida and we have everything growing down here. I started noticing results within an hour. The next day, I could tell which areas I didn't spray, or spray enough.

Definitely value for your money!!

I mixed the solution as instructed in a watering can and "watered" the weeds growing around our gravel parking lot, sidewalks, and walls that are really hard to pull out. Within 24 hours, the weeds were drooping, and within a few days they turned brown and shriveled up. It takes a little time, but it does a great job. I would recommend it!

I'm not sure how long this will work on weeds I sprayed, but it did work in the first 24 hours of application. For thicker patches of weeds, I'm not sure if they will ultimately grow back- time will tell. I'm hoping this is a semi-permanent solution to weeds.

Application was easy enough and the sprayer was convenient for even distribution.

5.0 out of 5 stars I was skeptical
Reviewed in the United States on May 22, 2024
I had my doubts on this product. But I gave it a go anyway. For the price at the time of purchase. It was not a great deal. Because after I had bought it from Amazon. Home Depot ran a BOGO deal on it. Back to its performance. It’s fantastic!!! I sprayed it in the morning. By evening I can already see some of the glass dying already. One tip. Don’t go easy on spray as it won’t cover enough to kill weeds. I sprayed it like i poured it. And wherever it hit. It won’t disappoint.

Purchased this for my side yard and front ditches. This thing is amazing! Have had other models in the past that come with a battery, but I have found those don’t spray as well. This you manually pump, but it has a nice spray mechanism and covers roughly 200sq ft. I noticed some of the weeds beginning to wilt in just a few hours. Will be purchasing the refill!

The Roundup Weed & Grass Killer with Pump 'N Go 2 Sprayer has been working great mostly in my yard maintenance routine. The convenient pump sprayer makes application a breeze, allowing me to target weeds and grass in flower beds, around trees, and other areas with precision. I've noticed visible results within days, as the formula effectively kills unwanted vegetation down to the root. It's been particularly effective in controlling persistent weeds and preventing them from regrowing. Plus, the large 1.33-gallon container provides ample coverage for my outdoor space, making it a cost-effective solution. However, I did notice some weeds stay survived after the first round of the spray and I had to spray them for a second time.
